HEATER.

Specification of Letters Patent.

Patented l.Tune 23, 1908.

To all whom it may concern:

Be it known that we, EDWARD J. DRoz, CHARLES A. DRoz, Sr., and CHARLES H. DROz, citizens of the United States of America, residing at Ambridge, in the county of Beaver and State of Pennsylvania, have invented certain new and useful Improvements in Heaters, of which the following is a specification, reference being had therein to the accom anying drawing.

T 's invention relates to heaters, and more particularly to a heater designed for heating halls and compartments, the heater being located beneath the floor of the hall or compartment to be heated.

The object of this invention is to provide a novel heater wherein gas is used for producing heat units, and in connection with the heater, we have devised novel means for causing a thorough radiation of the heat units within the heater prior to their admission to the hall or compartment to be heated.

Our invention -aims to utilize the centrifugal force of fans for distributing the heat units in a heater, the fan being suitably located to force heat units below the entire surface of a register, whereby these heat units when emit- 'ted from the register will be distributed in the room or compartment to be heated.

The invention will be presently described in detail, and then specifically pointed out in the appended claims.

Referring to the drawing forming a part of this specification, Figure 1 is a vertical sectional view of a heater constructed in accordance with our invention, Fig. 2 is a horizontal sectional view of a heater taken on the line -x of Fig. 1, Fig. 3 is a similar view taken on the line 'y-fy of Fig. 1, Fig. 4 is an elevation, partly in section of a fan used in con- Ilection with the heater, and Fig. 5 is a similar view of a slightly modified form of fan.

In the accompanying drawings, we have illustrated joists 1 as supporting a ioor 2 in which is located a conventional form of register 3.

Suspended below the register 3 is the heater proper, said heater comprising a cylindrical shell 4 supported in position by a plurality of straps 5, these straps being riveted to the lower edge of the she l, as at 6, and secured to the floor 2 as at 7.

The same rivets retaining the straps 5 in engagement with the shell 4 also serve for retaining angular supporting-brackets 8 in env gagement with the bottom edges of said Shell, said brackets supporting a cylindrical casing 9.

In the upper end of the casing 9 we rivet a fan frame 10, said fan-frame supporting a fan llhaving a plurality of blades. The fan as illustrated in Figs. 1 and 4 of the drawings is revolubly mounted in the depression 12 formed in the lower bar ofthe fan-frame 10, but this fan can be readily Suspended from a frame 10lrlL of the form illustrated in Fig. 5 of the drawings.

In order that the fan 11 can be cleaned any desired time or repaired, we provide the casing with a hinged door 14 directly beneath said fan, said door normally closing a doorway 15.

Approximately intermediate the ends of the casing 9 we arrange a baflie plate or grating 16, said casing being provided with a door-way 17 adjacent to said baiiile plate, whereby the baffle plate or grating can be cleaned. The door-way 17 is normally closed by a hinged door 18.

The bottom of the casing 9 is provided with brackets 19 for supporting a burner casing 20, this burner casing being cylindrical in form and having its ends covered with wire gauze 21. Gas is admittedto the burner casing 2O from a suitable gas supply pipe 22 arranged beneath the burner casing 20.

When the heater is in operation, the heat emitted from the burner casing is distributed through all parts of the casing 9 when passing through the baflie plate or grating 16, and as the heat units impinge the fan 10, the centrifugal force of this fan is adapted to further distribute the heat units within the shell 4, before they are finally ejected from the register 3 into the hall or compartment to be heated.

The baflie plate or grating 16 also serves to retard the heat roducts a suflicient time to permit of the cel ar or compartment in which the heater is located to become heated, and as said heater is suspended from the iloor of the compartment above, perfect safety is inregister at its upper end, a plurality of su said casing, and a burner casing carried by porting straps connected at their lower en y said support.
